minification with unbundle results in unoptimized output

[sakgoyal]

Reproduction link or steps

https://github.com/sakgoyal/case-anything/tree/tsdown

1. command run: tsdown --dts --sourcemap --minify --unbundle
2. check the index.d.ts file
3. check the index.js file

What is expected?

// index.d.ts
export { adaCase, /** ... */ upperCase } from "./core.js";

//index.js
export {adaCase, /** ... */ upperCase} from "./core.js";

What is actually happening?

// index.d.ts
import { adaCase, /** ... */ upperCase } from "./core.js";
export { adaCase, /** ... */ upperCase };

//index.js
import{adaCase as e,/** ... */ upperCase as m} from"./core.js";
export{e as adaCase,/** ... */ m as upperCase};

The d.ts file could be shorter to make it more "optimized"

Any additional comments?

Not really sure what to title the bug.
